Col003 is a selective and potent inhibitor of Hsp47and competitively binds to the collagen binding site on Hsp47 (IC₅₀=1.8 μM). Col003 discourages the interaction of Hsp47 with collagen and inhibits collagen secretion by destabilizing the collagen triple helix. Col003 can be used for the investigation of fibrosis^[1]

Col003 (4.4-40 μM) is cleaved from Col001 (AK-778). Col003 has an inhibitory effect on the interaction of Hsp47 with collagen in Hsp47 KO^–/–MEFs^[1].
Col003 (0.01-100 μM) exhibits dose-dependent effects on the interactions of Hsp47 with collagen. The IC₅₀ value is 1.8 μM for Hsp47^[1].
Col003 (100 μM; 20-60 mins) has an nhibitory effects on collagen secretion and accumulation. It inhibits collagen secretion by wild-type MEFs and the secretion is not abolished completely^[1].
Col003 (100 μM) degrades α,α′-dipyridyl collagen secretion completely by incubation with trypsin at a high temperature (50 ℃ for 15 min), but it resistant to trypsin digestion at 37 ℃^[1].

请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液；一旦配成溶液，请分装保存，避免反复冻融造成的产品失效。
储备液的保存方式和期限：-80℃, 6 months; -20℃, 1 month (stored under nitrogen)。-80℃ 储存时，请在 6 个月内使用，-20℃ 储存时，请在 1 个月内使用。

请根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都请先按照In Vitro方式配制澄清的储备液，再依次添加助溶剂：

——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议您现用现配，当天使用； 以下溶剂前显示的百
分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

• 1.

  请依序添加每种溶剂： 10% DMSO    40%PEG300   5%Tween-80   45% saline

  Solubility: 2.5 mg/mL (9.72 mM); Clear solution; Need ultrasonic

  此方案可获得 2.5 mg/mL (9.72 mM) 的澄清溶液。

  以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。

  将 0.9 g 氯化钠，完全溶解于 100 mL ddH2O 中，得到澄清透明的生理盐水溶液
